11 1/2”’ | Automatic | Swiss Lever | Direct Sweeping Seconds |

Remarks:

• This movement is a successor to the Badenia RA 127, but with a different base movement. According to Hampel, the base movement of the 1128 is supposed to be an FHF caliber. However, the base movement here is clearly identifiable as a movement by Hermann Becker. The calibers HB 114, 214, 314 and 414 come into question, all of which have manual winding and date, unfortunately I am not aware of any other differences
• The automatic unit is an in-house development by Badenia. However, it is not interchangeable between the RA 127 and 1128 movements. The automatic consists of an eccentric with two transport levers, similar to the Seiko Magic Lever, and is bidirectional winding. It drives the crown wheel
• An article in the Neue Uhrmacher-Zeitung from 1961 states that the Badenia 1128 should have a screw balance, 30 jewels and rubies as ball bearings for the rotor. The movement shown here, however, has a screwless balance, 25 jewels and steel ball bearings. So there seem to have been different variants. In the Flume K3, it is noted that the company changed the automatic unit several times
